Image Session Ranking

1. A method implemented by one or more computing devices, the method comprising: receiving indications that a plurality of image sharing sessions are available for joining by one or more potential members, the image sharing sessions being broadcast without manual management on the part of a creator; prioritizing the plurality of image sharing sessions based on each one of a plurality of ranking criteria that are usable to determine a relative likelihood that a user wishes to join respective said image sharing sessions, the ranking criteria being based on a combination of information from a plurality of different social networking accounts, information from a plurality of different non-social networking sources, as well as information from image sharing session history, the information used for each one of the plurality of the ranking criteria being given custom weighting by the user; and forming a first list of suggested image sharing sessions that are available for the user to join, the first list of suggested image sharing sessions arranged, one to another, based on the prioritizing.

2. A method as described in claim 1 , wherein one or more of the image sharing sessions are associated with an event and invitations to join the one or more image sharing sessions are retrieved by scanning of one or more quick response (QR) codes by the one or more computing devices.

3. A method as described in claim 1 , further comprising forming a communication for output via a user interface of a computing device of the user.

4. A method as described in claim 1 , wherein the receiving, the prioritizing and the forming are performed in real time based at least in part on a likely current location of the user.

5. A method as described in claim 1 , wherein the receiving, the prioritizing and the forming are performed by the one or more computing devices that are part of service provider that is available to a computing device of the user via a network.

6. A method as described in claim 1 , wherein the plurality of ranking criteria include at least one criterion that is based on a proximity of the user to an event associated with a respective said image sharing session.

7. A method as described in claim 1 , wherein the plurality of ranking criteria include at least one criterion that is based on whether another user associated with a respective said image sharing session is known to the user.

8. A method as described in claim 1 , wherein the plurality of ranking criteria include at least one criterion that is based on a number of members associated with a respective said image sharing session.

9. A method as described in claim 1 , wherein the plurality of ranking criteria include at least one criterion that is based on a number of likes or comments associated with a respective said image sharing session.

10. A method as described in claim 1 , wherein the plurality of ranking criteria include a number of images shared via a respective said image sharing session, a number of images associated with an event associated with a respective said image sharing event, or geographic data associated with a respective said image sharing event.

11. A method as described in claim 1 , wherein higher priority is given to people associated with the user through one particular social network than to people associated with the user through a different social network.

12. A method as described in claim 1 , further comprising forming a second list with indications of associated image sharing sessions that the user previously has joined as a member.

13. A computing device comprising: a housing having a mobile form factor; a display device disposed on the housing; and one or more modules disposed in the housing and implemented at least partially in hardware, the one or more modules configured to collect invitations to join respective ones of a plurality of image sharing sessions being broadcast without manual management on the part of an image sharing session creator and display a list of the image sharing session on the display device, the list having the plurality of image sharing sessions prioritized, one to another, based on a likelihood that a user will desire to join respective said sessions, the prioritization being based on each one of a plurality of ranking criteria, the ranking criteria being based on a combination of information from a plurality of different social networking accounts, information from a plurality of different non-social networking sources, and information from image sharing session history, the information used for each one of the plurality of ranking criteria for the prioritization being given custom weighting by the user.

14. A computing device as described in claim 13 , wherein the one or more modules are configured to communicate the collected invitations for receipt by a service provider via a network and received the list from the service provider.

15. A computing device as described in claim 13 , wherein the list is prioritized based on proximity of a user to an event associated with a respective said image sharing session.

16. A computing device as described in claim 13 , wherein the list is prioritized based on whether another user associated with a respective said image sharing session is known to the user.

17. A computing device as described in claim 13 , wherein the list is prioritized based on a number of members associated with a respective said image sharing session.

18. A computing device as described in claim 13 , wherein the list is prioritized based on a number of likes or comments associated with a respective said image sharing session, a number of images shared via a respective said image sharing session, a number of images associated with an event associated with a respective said image sharing event, or geographic data associated with a respective said image sharing event.

19. A system comprising: at least one computing device configured to perform operations comprising: prioritizing a plurality of image sharing sessions in real time based on each one of a plurality of ranking criteria that are usable to determine a relative likelihood that a user wishes to join respective said image sharing sessions, the ranking criteria being based on a combination of information from a plurality of different social networking accounts, information from a plurality of different non-social networking sources, as well as information from image sharing session history, the information used for each one of the plurality of the ranking criteria being given custom weighting by the user; forming a first list of suggested image sharing sessions in real time that is available for the user to join, the first list of suggested image sharing sessions arranged, one or another, based on the prioritizing configured for output in a user interface; and forming a second list with indications of associated image sharing sessions that the user previously has joined as a member.

20. A system device as described in claim 19 , wherein the first list is prioritized based on: proximity of a user to an event associated with a respective said image sharing session; whether another user associated with a respective said image sharing session is known to the user; a number of members associated with a respective said image sharing session; a number of likes or comments associated with a respective said image sharing session; a number of images shared via a respective said image sharing session; a number of images associated with an event associated with a respective said image sharing event, or geographic data associated with a respective said image sharing event.
